Sprawling lush green hills? Can’t beat Chino Hills State Park.
The campground itself feels very close together and wide open compared to the space of the park. Gets loud at night if there are too many groups camping. No cell service. Super clean bathrooms and showers.

PET OWNERS BEWARE: Our dog munched on a frog at this campsite and started foaming at the mouth. We rinsed her mouth out with water and she turned out fine, but a smaller dog or a swallowed frog and she could have died from toxicity.
